This free program written by me, Andrew Rowbottom,
uses a simple language to construct the organic objects. Form comes with a fairly quick on-screen
previewer in grey scale. These shapes can be mutated, mutations can
be selected on screen and saved, or new mutation created based on the selected shape. In normal mode
the preview screens can be saved as gif. For qulaity rendering some other sort of output must be generated.
It is also possible to morph between different mutations, saving each screen to produce an animation.
Form produces output for POV, DXF, VRML and VIVID.

This free program written by Laurens J. Lapre uses "L-systems" to produce shapes,
an l-system is a rule like description of a 3d form, fractal and recursive forms are very easy to describe in an l-system.
These L-systems, which to me seem very abstract, can produce quite intricate shapes.
These shapes can be mutated, and I'm not sure but I think it may be possible to produce sequences of
frames between mutations for animation.
Lparser also comes with a good quality 3D full perspective previewer which can produce
camera information for POV.
Lparser can produce POV, VIVID and DXF output.

This program is a Web based implementation of Richard Dawkins Biomorph program.
I'm still looking for a link to the real thing!
For more information on biomorphs see Biomorph below,
or follow the link to the interactive biomorph page.

Doodle Garden uses a technique called Genetic Programming to evolve
new drawings.
A small computer program draws each doodle. You can Mutate (randomly
change) a doodle program, or you can Cross programs (attach part of
one to part of another) with interesting results. You guide this
process by selectively breeding your favorite doodles.
Click on your favorite doodle and a Button Bar will appear. This bar
protects the doodle during breeding. You use the buttons to mutate,
cross, load, save or view a doodle. You can gain more control over
your results by adjusting the breeding parameters and drawing
functions.
Animate will automatically generate new doodles every few seconds by
mutating and crossing the currently protected doodles. You can even
use it as a Screen Saver.
Doodle Garden starts with random graphics. For best results, we
suggest that you start by loading a previously saved doodle. Just
push the buttons on your favorite doodles to explore Genetic
Programming and a fascinating visual space.

this is an attempt to reproduce a Karl Simms Genetic Images program in 256 colours.

Basically I found that this was quite a fun program with a polished interface, unfortunately the code doesn't go far enough, there is no way to save or reload the "program" that make up a picture. I also had problems saving the pictures as bitmaps, the whole program gives a feeling of being unfinished, I'm trying to contact the author to see if there is a more recent version around.

Introduction derived from the Help file

Imogene lets you interactively generate pictures which dynamically adapt to your own aesthetic sense over successive generations using genetic programming.
Each generation contains 9 images laid out in a 3x3 grid. Each of the 9 images is generated by a mathematical formula which is applied to each (x,y) co-ordinate in the image to produce a palette index (and thus a color) for that co-ordinate.
In the first generation, the formulae are generated randomly based on a set of primitive formula elements, such as addition, subtraction, logical bitvector operations, and the formula input (the x and y co-ordinates). The neat thing is that, for most formulae, the pattern which results from the application of the formula to all the points in the image is coherent and sometimes even beautiful.
In generations after the first, the formula for each image is no longer generated randomly. Instead, for each image, two formulae are chosen from the previous generation. These formulae are combined and mutated to form a new formula. The chances of a formula being selected are based on its fitness.

The user interface is not too complicated, but I did have to skim through the short but adequate doc file to control the program properly. Unfortunately I have been unable to actually produce any POV output from this program.

Cybertation is a cheap (10 UK pounds) program that was released with the
Evolution of Life CD Rom
which creates complex 3D coloured "animals". You can mutate and cross breed these to produce
wonderfully complex children.
The "animals" are created on screen in full colour, full 3D, multitasking real time,
although you can lower the quality of output to suit the complexity of the organism and you machine.
There is a good selection of starting points for your exploration.
Tip: clicking on an area outside an object allows you to add more "mutated children" to view and cross breed.

A professional piece of software although the help file is just a small text file
the program doesn't really warrant any more.

repliGATOR is a stand-alone program which takes already existing digital images (scanned photographs, files from
digital cameras, computer generated graphics, etc.) and changes them with Object Xforms into new image ideas.
It can be used in an evolutionary manner, by using the "wizard" Function key 7
really, and repeating until a suitable variant is found, re-using variant as the basis
for another sequence of variants. Its primary purpose is to create logo-like
images based on an already existing plain image.
Although the demo version was a beta version I had absolutely no problems with it.

A Commercial implementation of Biomorphs (also known as "The Blind Watchmaker Softwareo")
is available from
W. W. Norton & Company, Inc. although I have not seen it in action.
I also have seen a conversion for IBM PC compatibles by SPA Ltd
of a program designed and written by Richard Dawkins to demonstrate
how even simple seemingly arbitrary selection could produce intricate
apparently "designed" objects. An excellent primer program.

Biomorphs are computer generated creatures whose evolution
you can examine and control using selection, drift and
'genetic engineering'.
When the computer draws a biomorph it is really drawing a
simple branching tree. However, these simple trees give rise
to an extraordinary variety of biomorph shapes, some
abstract, many biological, sometimes grotesque, and often
very beautiful.
The shape of a biomorph is under the influence of nine
genes, each of which has a value represented by a number.
The numbers influence the shapes because some genes affect
the angle of tree branching, others the lengths of the
branches, the angles and lengths being taken from the
numbers.
The biomorphs can reproduce asexually, and when they do
their children carry random mutations. That is, their gene
values differ slightly from their parents. The USER SELECTS
option in the EVOLVE menu allows you to choose one of the
litter of mutant progeny from which to breed. You can then
choose one of its children in turn as a new parent and so on
generation after generation.I am trying to discover the commercial availabilty of this program

Following from Henrik Hautop Lund one of the authors, the Homepage also has a limited interactive demo.

The Artificial Painter derives from our Artificial Life simulations
using Genetic Algorithms on Neural Networks that represents small
organisms (see e.g. my paper in Artificial Life 2:2). The Artificial
Painter was originally developed as a research project financed by
ABACO s.r.l. and the Italian National Research Council. Later,
there appear to be great public interest in the Artificial Painter,
so we are now negotiating with different companies like Benetton,
Swatch and Sector on selling the rights or licenses to the use
of the program. Further, the artist V. Vucic from ex-yugoslavia
is using the Artificial Painter (on a special license) as a way
of new enformel or non-figurative painting. His project is
connected with multidimensional perception and developing skills
for dynamic and contextual thinking and percpetion which is crucial
for those who suffer from trauma or for those who face a lack
of information and positive stimuli from their environment.
